HIGH W007: Insecure credential handling detected in skill instructions.

• Insecure credential handling detected (high risk: 1.00). The audit spec requires extracting and formatting env/default values (e.g., format_defaults, example_vars with values, default_value) and includes them in findings/report, which forces the LLM to read and potentially emit secret values verbatim.
